What is the range of the 5-point severity scale used to rate psychosis symptoms?

• A. A 7-point scale from 0 to 6
• B. A 3-point scale from 0 to 2
• C. A 10-point scale from 0 to 9
• D. A 5-point scale from 0 to 4

Answer: (D)

A five-point severity scale spans five levels, from 0 to 4. This means the symptom rating ranges from 0, meaning the symptom is absent, up to 4, representing the highest level of severity within this scale. The scale provides enough granularity to distinguish between no symptoms, mild, moderate, and more severe presentations without being overly detailed. The other options describe scales with different total numbers of points (7-point, 3-point, 10-point), which do not fit the five-point system.
